Mns Low-Voltage Withdrawable Switchgear Oil Transformer Power Distribution Cabinet

MNS LV withdrawable switch gear (hereinafter rferred to as device) is manufactured by standard module through consulting MNS series low voltage switch cabinet of Switzerland ABB Co-transmission, distribution, power transfer and power consumption device. It is widely used in low voltage distribution system of various mining enterprise, tall building and hotel, municipaltransmission, distribution, power transfer and power consumption device. It is widely used in low voltage distribution system of various mining enterprise, tall building and hotel, municipal construction etc. Besides the gencral land use, after special disposal, it also can be used for marine petrol drill taken platform and nuclear power station.The device accords with international standard IEC439-1 and national standard GB7251.1.
1. Compact design: Contain more function units with less space.

2. Strong versatility for structure, flexible assembly. C type bar section of 25mm modulus can meet the demands of various structure and type,          protection grade and operating environment.

3. Adopt standard module design, can be combined into protection, operation, transfer, control, regulation, measurement, indication etc such standard units. User can choose assembly according to requirement at will. Cabinet structure and drawer unit can be formed with more than 200 components.

4. Fine security: Adopt high strength antifaming type engineering plastic pack in large quantity to efctivelte enhance the protective safety performance.

5. High technical performance: Main parameters reach the advanced level at home.

Structural features
The basic cabinet of device is combined assembly structure. Basic structural pieces of cabinet is zinc plated, connected and firmed into basic bracket through self tappinglocking serew or 8.8 grade square corner screw. According to the change demand of project, aditinally add corresponding gate, closing board,bafle plate, installationsupport and the components ofbus bar, function units, to assemble a complete set of device. Perform modulus to interior component and compartment size (Modulus unite- 25mm).
